The U.S. Department of Energy is proposing to provide funding to Colorado State University (CSU) to make modifications to the existing CSU sublimation system so a thin film of cadmium selenium telluride (CST) alloy can be deposited on solar cells to achieve higher lifetime and efficiency of cells.
Project activities include: design, assembly and minor modification to the Advanced Research Deposition System (i.e. sublimation system) to allow for controllable deposition of CST using existing software; fabrication of devices containing graded CST layers; and characterization of the layers to understand the grain structure and selenium profile.
